    "options": [
      "通过在市场高点投入更多资金来最大化收益。",
      "基于“平均成本法”，通过在固定时间投入固定金额来平滑市场波动对成本的影响。",
      "选择在特定日期一次性买入，以期获得最低的买入价格。",
      "完全依赖基金经理的择时能力来规避市场风险。"
    ],
    "correctAnswerIndex": 1,
    "explanation": "文档明确指出，「定期定额投资」的原理基于“平均成本法”。这意味着无论市场价格高低，投资者都定期投入固定金额。当价格低时，能买到更多份额；价格高时，买到的份额较少。长期下来，这可以有效平均投资成本，降低在市场高点一次性买入的风险。",
    "source": "文档中「（二）定期定额投资」部分",
    "hint": "这种投资方式旨在通过长期、持续的小额投入，有效降低市场波动对投资成本的影响。"

    "question": "文档提到了债券投资存在的两种主要风险，它们分别是什么？",
    "options": [
      "市场波动风险和政策风险",
      "通货膨胀风险和流动性风险",
      "利率风险和信用风险",
      "操作风险和汇率风险"
    ],
    "correctAnswerIndex": 2,
    "explanation": "文档中详细解释了债券的两种主要风险。利率风险是指当市场利率上升时，现有债券的吸引力下降，价格可能下跌。信用风险则是指发行方（特别是企业）因经营不善而无法按时支付利息或偿还本金的风险。",
    "source": "文档中「（二）债券」部分",
    "hint": "一种风险与市场整体利率变化有关，另一种与债券发行方的偿债能力有关。"
  },

      "设置止盈止损",
      "分散投资",
      "长期投资"
    ],
    "correctAnswerIndex": 2,
    "explanation": "文档明确将“不要把所有的鸡蛋放在一个篮子里”作为「分散投资」策略的简单解释。该策略的核心是通过将资金分配到不同的资产类别、地域和行业中，来对冲单一投资表现不佳时带来的整体损失，从而实现风险的有效分散。",
    "source": "文档中「（一）分散投资，降低风险」部分",
    "hint": "该策略的核心在于通过将资金分配到不同的资产类别、地域、行业中，实现风险的有效分散。"
  },

    "question": "根据文档，对于临近退休、风险承受能力较低的投资者，通常更倾向于哪类投资产品？",
    "options": [
      "股票等高风险高回报资产",
      "混合型基金以平衡风险与收益",
      "债券、定期存款等稳健型产品",
      "新兴产业的股票以追求长期增值"
    ],
    "correctAnswerIndex": 2,
    "explanation": "文档在论述风险承受能力时指出，年龄是重要影响因素之一。临近退休的人更注重资产的保值和稳定的现金流，因此风险承受能力相对较低，投资会倾向于像债券、定期存款这类风险较低、收益稳健的产品。",
    "source": "文档中「（二）了解风险承受能力」部分",
    "hint": "这类投资者更注重资产的保值和稳定现金流，而非高风险带来的高回报潜力。"
  },
  {
    "question": "文档将哪种情绪描述为投资中的“大敌”，并可能导致投资者在市场下跌时“在低位割肉”？",
    "options": [
      "贪婪 (Greed)",
      "恐惧 (Fear)",
      "乐观 (Optimism)",
      "犹豫 (Hesitation)"
    ],
    "correctAnswerIndex": 1,
    "explanation": "文档强调，“恐惧同样是投资的大敌”。当市场下跌时，恐惧情绪会迅速蔓延，导致投资者陷入过度悲观，匆忙抛售资产以避免进一步损失。这种恐慌性抛售行为，常导致投资者在市场低点卖出（即“割肉”），从而错失市场反弹的机会。",
    "source": "文档中「（一）保持理性投资」部分",
    "hint": "当市场出现波动或下跌时，这种情绪会迅速蔓延，投资者往往会陷入过度悲观的状态。"

      "公司高管的媒体曝光度和新闻数量",
      "股票的交易活跃度和换手率"
    ],
    "correctAnswerIndex": 1,
    "explanation": "在「长期投资策略」部分，文档明确指出选股至关重要，并列出了三个关键考量因素：企业是否具有强大的竞争优势（如品牌、技术），是否具备持续稳定的盈利能力（通过财务指标评估），以及是否处于一个前景广阔的行业。",
    "source": "文档中「（一）长期投资策略」部分",
    "hint": "选股时需要关注企业的核心竞争力、财务健康状况以及其所在赛道的发展潜力。"
  },
  {
    "question": "“设置止盈止损”策略的主要目的是什么？",
    "options": [
      "预测市场的最高点和最低点",
      "频繁交易以增加投资的刺激性",
      "作为“安全阀门”，帮助投资者锁定利润和限制亏损",
      "完全自动化交易，无需人工干预"
    ],
    "correctAnswerIndex": 2,
    "explanation": "文档将止盈和止损比作投资的“安全阀门”。其核心目的在于风险管理：止盈是在收益达到预设目标时卖出，将浮动盈利变为实际收益；止损则是在亏损达到预设幅度时卖出，防止亏损进一步扩大。这是一种纪律性的操作，用于克服人性的贪婪与恐惧。",
    "source": "文档中「（三）设置止盈止损」部分",
    "hint": "这个策略可以帮助投资者在市场波动中有效控制风险，锁定利润。"

      "收益相对稳定，风险较低",
      "能灵活配置股票和债券的比例"
    ],
    "correctAnswerIndex": 2,
    "explanation": "文档在介绍基金类型时明确对比了几种基金的特点。其中，债券型基金以债券投资为主，其主要特征是收益相对稳定，风险较低，因此更适合追求稳健收益的投资者。而高风险高收益是股票型基金的特点，灵活配置则是混合型基金的特点。",
    "source": "文档中「（三）基金」部分",
    "hint": "这种类型的基金比较适合追求稳健收益的投资者。"
